실시예 1: CLP 패혈증 모델에서 라이소포스파티딜콜린의 효과Example 1 Effect of Lysophosphatidylcholine in CLP Sepsis Model

실시예 1aExample 1a

참고예 1(a)에 따른 CLP 패혈증 모델의 ICR 마우스 40마리를 봉합한 지 2 시간 후부터 12시간 간격으로 4회에 걸쳐, 각 10마리의 ICR 마우스에게는 1 회씩 지방산이 없는 1% BSA(bovine serum albumin) 용액에 녹인 L-α-라이소포스파티딜콜린, 스테아로일 (Sigma)을 5, 10, 20㎎/㎏의 양으로 복강 투여하고 (실험군), 나머지 10마리의 ICR 마우스에게는 지방산이 없는 1% BSA 용액 만을 투여하였다 (대조군). 시간이 경과함에 따른 실험군 및 대조군의 ICR 마우스의 생존율을 조사하였고 그 결과는 도 1a에 도시하였다. 도 1a에서 알 수 있듯이, 라이소포스파티딜콜린을 투여한 실험군의 마우스들은 대조군의 마우스들에 비하여 생존율이 훨씬 높았다. 40% ICR mice of the CLP sepsis model according to Reference Example 1 (a) were subjected to 4 times at 12 hour intervals from 2 hours after suture, and 1% bovine serum without fatty acid once in each 10 ICR mice. L - α -lysophosphatidylcholine and stearoyl (Sigma) dissolved in the albumin solution were intraperitoneally administered in an amount of 5, 10, 20 mg / kg (experimental group), and the remaining 10 ICR mice had 1% free of fatty acids. Only BSA solution was administered (control). The survival rate of the ICR mice in the experimental and control groups was examined over time, and the results are shown in FIG. 1A. As can be seen in Figure 1a, mice in the experimental group administered lysophosphatidylcholine had a much higher survival rate than the mice in the control group.

실시예 1bExample 1b

라이소포스파티딜콜린이 패혈증이 진행된 경우에도 효과가 있는지를 관찰하기 위하여, 참고예 1(a)에 따른 CLP 패혈증 모델의 ICR 마우스 20마리를 CLP후 10시간 후부터 12시간 간격으로 4회에 걸쳐, 10마리의 ICR 마우스에게는 1 회씩 지방산이 없는 1% BSA 용액에 녹인 L-α-라이소포스파티딜콜린, 스테아로일 (Sigma)을 10㎎/㎏의 양으로 복강 투여하고 (실험군), 나머지 10마리의 ICR 마우스에게는 지방산이 없는 1% BSA 용액 만을 투여한 (대조군) 후에, 시간이 경과함에 따른 실험 군 및 대조군의 ICR 마우스의 생존율을 조사하였고, 그 결과는 도 1b에 도시하였다. 도 1b에서 알 수 있듯이, 패혈증이 더 진행된 경우에도 라이소포스파티딜콜린은 거의 동일한 치료효과를 유지하였다. In order to observe whether lysophosphatidylcholine was effective even when sepsis progressed, 20 ICR mice of the CLP sepsis model according to Reference Example 1 (a) were divided into 10, four times at 12 hour intervals from 10 hours after CLP. ICR mice were intraperitoneally administered L - α -lysophosphatidylcholine and stearoyl (Sigma) dissolved in 1% BSA solution without fatty acid at a dose of 10 mg / kg (experimental group), and the remaining 10 ICR mice After administration of 1% BSA solution without fatty acid (control), the survival rate of ICR mice in the experimental and control groups was examined over time, and the results are shown in FIG. 1B. As can be seen in Figure 1b, lysophosphatidylcholine maintained almost the same therapeutic effect even if further sepsis.

1-스테아로일 라이소포스파티딜콜린과 아실기 (화학식 1의 R1기)가 상이한 라이소포스파티딜콜린도 패혈증에 효과가 있는지를 알아보기 위하여, 1-스테아로일 라이소포스파티딜콜린 대신에 각각 1-올레오일(18:1) 라이소포스파티딜콜린 및 1-미리스토일(14:0) 라이소포스파티딜콜린을 10㎎/㎏의 양으로 복강 투여하는 것을 제외하고는 실시예 1a와 동일한 방식으로 시험하였고, 그 결과를 도 1c에 도시하였다. 도 1c에서 알 수 있듯이, 1-스테아로일 라이소포스파티딜콜린과 아실기가 상이한, 1-올레일(18:1) 라이소포스파티딜콜린 및 1-미리스토일(14:0) 라이소포스파티딜콜린도 패혈증에 대해 우수한 치료효과를 나타냈다. To determine whether 1-stearoyl lysophosphatidylcholine and the acyl group (R 1 group of formula 1) are effective for sepsis, 1-steoyl lysophosphatidylcholine, instead of 1-oleoyl, respectively (18: 1) Lysophosphatidylcholine and 1-myristoyl (14: 0) lysophosphatidylcholine were tested in the same manner as in Example 1a except for intraperitoneal administration of 10 mg / kg. It is shown in Figure 1c. As can be seen in FIG. 1C, 1-oleyl (18: 1) lysophosphatidylcholine and 1-myristoyl (14: 0) lysophosphatidylcholine, which differ from 1-stearoyl lysophosphatidylcholine and acyl groups, also for sepsis Excellent therapeutic effect was shown.

Twenty ICR mice of the CLP sepsis model according to Reference Example 1 (a) were dissolved in L - α -lysophosphatidylcholine and stea at 2 and 12 hours after CLP and in 10% ICR mice in 1% BSA solution without fatty acids. Loyl (Sigma) was administered intraperitoneally in an amount of 10 mg / kg (experimental group), and the remaining 10 ICR mice received only 1% BSA solution without fatty acid (control). These mice were anesthetized after 24 hours of CLP, exposed to the abdominal cavity, and then washed with each sterile saline solution (2 ml), diluted 1/1000 with sterile saline solution again, and 10 μl of each diluted solution was Trypticase Soy agar. (BD BBL, USA) Plates were plated, incubated overnight at 37 ° C., and the number of colonies (Colony Forming Unit (CFU)) was measured. The average values are shown in FIG. 1D. As shown in FIG. 1D, mice in the experimental group administered with lysophosphatidylcholine reduced the number of intraperitoneal bacteria by 80% compared to the control group.

실시예 1bExample 1b

참고예 1(b)에 따른 세균-유발 패혈증 모델의 ICR 마우스 20마리를 봉합한 후, 2 시간 및 12시간에 10마리의 ICR 마우스에게는 지방산이 없는 1% BSA 용액에 녹인 L-α-라이소포스파티딜콜린, 스테아로일 (Sigma)을 10㎎/㎏의 양으로 복강 투여하고 (실험군), 나머지 10마리의 ICR 마우스에게는 지방산이 없는 1% BSA 용액 만을 투여하였다 (대조군). 그리고 나서 실시예 1d에서와 같이, 이들 마우스들의 복강액내의 세균 수(CFU)를 측정하여, 그 결과를 도 2b에 나타내었다. 도 2b에 도시된 바와 같이, 라이소포스파티딜콜린이 투여된 실험군의 마우스들에서는 대조군과 비교하여 복강내 세균의 수가 현격히 감소되었다.
After suturing 20 ICR mice of the bacterial-induced sepsis model according to Reference Example 1 (b), 10 ICR mice were dissolved in L - α -lyso dissolved in 1% BSA solution without fatty acids in 10 and 12 hours. Phosphatidylcholine, stearoyl (Sigma) was administered intraperitoneally in an amount of 10 mg / kg (experimental group), and the remaining 10 ICR mice received only 1% BSA solution without fatty acid (control). Then, as in Example 1d, the bacterial counts (CFU) in the peritoneal fluid of these mice were measured, and the results are shown in FIG. 2B. As shown in Figure 2b, mice in the experimental group administered lysophosphatidylcholine significantly reduced the number of bacteria intraperitoneally compared to the control group.

실시예 3: LPS-유발 패혈증 모델에서 라이소포스파티딜콜린의 효과Example 3: Effect of Lysophosphatidylcholine in LPS-Induced Sepsis Model

참고예 1(b)에 따른 LPS-유발 패혈증 모델의 ICR 마우스 20마리를 대장균 주사 2시간 후부터 12시간 간격으로 4회에 걸쳐, 10마리의 ICR 마우스에게는 지방산이 없는 1% BSA용액에 녹인 L-α-라이소포스파티딜콜린, 스테아로일 (Sigma)을 10㎎/㎏의 양으로 복강 투여하고 (실험군), 나머지 10마리의 ICR 마우스에게는 지방산이 없는 1% BSA 용액 만을 투여하였다 (대조군). 시간이 경과함에 따른 실험군 및 대조군의 ICR 마우스의 생존율을 조사하였고 그 결과를 도 3에 도시하였다. 도 3에서 알 수 있듯이, 라이소포스파티딜콜린을 투여한 실험군의 마우스들은 대조군의 마우스들에 비하여 생존율이 훨씬 높았다. Note dissolved in example 1 (b) over the ICR mouse 20 of LPS- induced sepsis model in four times every 12 hours after injection of E. coli two hours, without a fatty acid for ICR mouse of 10 1% BSA solution in accordance with the L - α -lysophosphatidylcholine, stearoyl (Sigma) was intraperitoneally administered in an amount of 10 mg / kg (experimental group), and the remaining 10 ICR mice received only a 1% BSA solution without fatty acid (control). The survival rate of the ICR mice in the experimental and control groups over time was examined and the results are shown in FIG. 3. As can be seen in Figure 3, mice in the experimental group administered lysophosphatidylcholine had a much higher survival rate than the mice in the control group.

실시예 1~3의 결과로 부터 라이소포스파티딜콜린 및 그 유사체는 패혈증의 예방 및 치료 효과를 가짐을 확인할 수 있었다.
From the results of Examples 1 to 3, it was confirmed that lysophosphatidylcholine and its analogs have the effect of preventing and treating sepsis.
